BOWLING ALLEY PIT CUSHION STRUCTURE Filed Oct. 17, 1927 Fatented May 12, 1931 UNITED STATES PATENT OFFICE THEODORE R. TREIBER, OF CHICAGO, ILLINOIS, ASSIG-NOR, BY MESNE ASSIGNMENTS, TO THE BRUNSVTICK-BALKE-COLLENDER COMPANY, A CORPGR-ATION OF DELAWARE BOWLING ALLEY IIT CUSHION STRUCTURE Application filed October 17, 1927.

In use, the portion of a bowling alley pit cushion adjacent the plane of the alley becomes worn quickly while other portions of the cushion are not worn, and it is one. of the objects of my invention to provide means whereby the pit cushionmay be vertically reversed in order to present different portions of the cushion to the area of greatest wear for obvious reasons.

Another object of the invention resides in the provision of a pivotal support for bowling alley pit cushions by means of which the cushions may be easily and quickly installed or removed.

The invention will be better understood by reference to the accompanying drawings, in which Figure 1 is a cross sectional view of the pit portion of a bowling alley with parts broken away and in section;

Figure 2 is an enlarged partial plan view of the same;

Figure 3 is a perspective view of one of the pivot members of the structure;

Figure 4 is a perspective view of another portion of the pivot structure with a part broken away.

Like characters of reference indicate like parts in the several views.

Referring to the drawings, 1 designates a bowling alley pit structure having sides or kick backs which support a rectangular pit cushion 2. The cushion 2 comprises as usual a wood frame or backing 3 on the front of which is attached a cushion structure 4 which is preferably divided horizontally as shown.

The frame 3 of the cushion 2 is provided with a continuous groove 5 about the sides thereof, and a U-shaped member 6 embraces three sides of cushion and is engaged in this groove, the member 6 being secured to the cushion by means of screws 7. See Figures 1 and 2.

Alined outwardly projecting pivot pins 8 are attached to the ends of the member 6, see Figures 1, 2, and 4, and U-shaped pivot brackets 9, see Figures 1, 2, and 3, are secured in upright positions on the kickbacks for engagement with the pins 8, thus providing a pivot mounting for the cushion, by means of Serial No. 226,592.

which the cushion is easily installed or removed.

In the use of the device, when the lower portion of the cushion becomes worn, the screws 7 are taken out and the cushion turned upside down thus bringing what was originally the upper portion of the cushion into position to sustain most of the pounding from the balls and pins.

While I have herein shown and particularly described the preferred embodiment of my invention I do not wish to be limited to the precise details of construction shown as changes may readily be made without departing from the spirit of my invention, but having thus described my invention I claim as new and desire to secure by Letters Patent the following In a bowling alley pit cushion structure the combination with a rectangular pit cushion having a continuous groove about the sides thereof, of U-shaped pivot members adapted to be attached in upright positions to stationary means at the ends of the cushion,

a right angled U-shaped supporting member embracing three sides of the cushion and engaged in said groove and adapted for reversal thereon and to be secured therewith, and alined outwardly projecting pivot pins secured at the ends of said supporting member for engagement in said first mentioned pivot members to pivotally support the cushion.

'In witness whereof I hereunto afiix my signature this tenth day of October, 1927.
